- You receive a fixed quote covering scope, products and sequence.

About our construction mastic in Haslingbourne
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old, and on older buildings we ask for the asbestos survey before disturbing anything. After that, the joints are prepared and sealed to the specification. The enquiries we see most involve bath and shower joints scraped during the final clean and oversized or tapered gaps around new frames, on floor and skirting junctions, window and door perimeters and cladding and panel joints. A single leaking joint is often how a building in Haslingbourne first comes to us: we look at the rest while we are there and tell you what we find.
Around smaller places like Haslingbourne, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

When to call us in Haslingbourne
Most mastic snags on new buildings come from sequencing rather than product. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage.
Any of the following is a good reason to get the joints checked over:
- Different trades sealing to different standards
- Internal caulk splitting as the building dries out
- Missed perimeter joints on a new elevation
- Frame gaps too wide for sealant alone
Hotel extensions and refits, at places such as The Angel Hotel (0.9 miles north of Haslingbourne), typically run between busy periods, so the sealing is squeezed into short windows.
Comparing quotes
- Their approach to joint depth and backing
- Whether old or failed sealant will be cut out, not overlaid
- Proof of insurance
- Which product they’ll use, and why it suits the joint
Keeping the joints sound
Once the work is signed off, these steps help:
- Release areas for mastic once other trades have finished in them
- Protect sealed areas from following trades
- Stick to the specified sealant rather than a generic substitute
- Ask installers to correct oversized gaps first
A new structure shifts as it loses construction moisture. Flexible sealants in the right joints handle normal movement, but caulk in a joint that moves more than expected may crack. We can advise if a joint needs a different product.
Sealing outside when the joint is damp or too cold leads to poor adhesion. Waiting for a dry joint and the right temperature is better than redoing work, so we plan external work with that in mind.
Different surfaces, different methods
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer and we install what’s specified.
Window and door perimeters
A frame gap that’s too wide can’t just be filled with sealant. Gaps outside the product’s range are raised with the site team before sealing starts.

Questions we’re asked in Haslingbourne
Can you keep pace with our programme in Haslingbourne?
Yes, we work to the programme and the sequence the site sets. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is Haslingbourne too far out for you?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Will you stick to the specified products?
We follow the specified sealant and flag anything that doesn’t look right for the joint. Product standards such as BS EN 15651 are often named in specifications.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
How do you work with the site programme?
The programme sets the job. Tell us the sequence and we’ll plan applicators around it so sealing follows the trades.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
